GAUGNG MACHINE.

Application led October S, 1920.

To ald whom t may coince/rn.'

Je it known that l, HANS LU'rZ, residing at Elmira, county olf Chemung, State of New York, have invented certain new and useful Improvements in Gauging Machines, of which l declare the following to be a full` clear, and exact description.

My invention relates to gauging machines and has for its object to provide improved means for testing tools or other objects having :i series of splines or projections thereon, the accuracy of the spacing of which it is desired to test or determine.

A further object of the invention is to provide an improved gauging or Vtesting machine for indicating whether or not the distances between certain predetermined points upon an object are equal to or greater or less than predetermined standards ofk measure. j

A further object of the invention is to provide a testing device having a fixed member and a movablemember associated with an indicator for indicating whether or not the distance between two points on an object is greater or less than a predetermined distance.

With these and other objects in view the invention comprises certain novel features of construction and arrangement of parts as will be hereinafter more fully pointed out 'and claimed, it being apparent. to those skilled in the art that the invention shown and described herein is susceptible to various modifications and arrangements to suit special or varying conditions and 1 wish it to be understood that the terms which I have used are merely descriptive and not limiting and that it is my intention to include any and all modiications which fall within the scope of the invention as defined in the apA` pendod claims.

Ai construction constituting one embodiment of the invention is illustrated in the ac-` companying drawings of which:

'Figure l is a side elevation of a machine embodying the invention.

Figure Il is an-end elevation of the same with certain parts omitted.

r1`he machine illustrated in the accompanying drawings comprises a base 10, provided at one end with a raised portion 11, the base being preferably of `L-shaped construction as shown in Figure lV. Secured upon one end of the base is an upright 12, having a bearing member 13, mounted thereon into which is driven a tapered pin 14, upon the inner end of which is rotatively mounted the object 15 to be gauged or measured, which in the present instance constitutes a reaming tool provided with the splines or blades 16 upon one 'end thereof, the opposite end of the tool being supported by a tapered pin 17, driven into the slide 18 movable between the guides 19 disposed upon the raised portion 11, of the hase and secured thereon by means of the bolts 20, as indicated in Figure lll. The slidev18 is provided with a longitudinally extending recess 21, within which is helda spring 22 seated upon the end of an adjustable member Q3, having a head 24 slidably mounted within a groove 25 formed upon the raised portion 11, of the base as shown Vin Figures IH and V, said head being;- clamped in any desired position of adjustment by means of a bolt 26, the head of which is positioned within the undercut portion' 2T. of thegroove as indicated in upon the bearing 13, of the upright 12 is a slee-ve 27 having an annular flange 28, as shown iii `1 F i Oure by means of the screws 31, uwhich "are threaded into the inner end of the bearing 13 as shown in Figure V. Secured upnthe annular flange 28, of the sleeve 27 is the circular portion 32 of a lever 33,*slaid'circular'v portion being vdisposed upon the annular llangeQS anil'secured by'ine'ans Vofthe screws 34. Adjustably mountedupon the base ,10,l is a slide 35 whiclirnaybeclamped inany desiredposition by the means of'fa`boltf86,

the/head o'fywhichis'disposed in 'an under- Y, l lv Y y ,l 'v cut groove 3i formed 1n the base as shown inll bolt 40.` Throughthe yupper end of the block.

39 is threaded ascrew 41, the end of the block beingsplit to receive said screw 4which is held yinthe desired position by means of a clampingl bolty 43,` extending transversely throughf the split eiid of thel block. Secured upon'the lever 33, adjacent the inner end thereofisa plate 44, haying a groove in its outerifacetorece'ive 'a barl45 provided with a linger '46 at one vend thereof, said bar beingfhel'd Ein position upon the plate 44, by nieansfof' al clamping member 47, which is secured vby ymeans of the screws 48. 'The inger'46,ji`s adapted *to engage one ofthe splineserprojections'of the reamer `1.5 while the1 ustable screw 41 yis adapted to engage the next'succeeding spline immediately beneath the one engaged bythe finger as clear'- ly sho'wniu Figure V1, itV being understood that the screw '41:isadjustable to varyl the distance between Athe lowerend thereof and the `finger 46"to accommodate tools having splines orprojections spaced at greater or lesser distances apart than shown in Figure V11" ln'other words, the distances between the two Contact points, which engage the sides ofthesplines orjprojections may ber Secured upon 'the base adjacent the outer end lof `the lever 33 is a post 49, provided at its ripper end with a telescoping slide in the form ofa sleeve 50, the lower end of the sleeve being split and having projections 51,

tbrough'which extends ascrew 52, for

clamping the sleeve in any desired position upon-tl'legpostz` The sleeve is made adjustable upon the post by means of a feed screw 53 threaded through a block 54, anchored in a recess inthe upper end of the' post as showniir Figure VlILsaid screw being swiveled in ythe outer end of `the sleeve as indicat'edat 55and provided with a knob 56 y 'The sleeve 2'5"'is hfeld': upon thebearihgll by meanslof ajplate 29 disposed within a recess on the inner-"endV ofgthe' sleeve 2?@ thersame -being secured for turning the screw. The sleeve is prevented from turning upon the post by means of altey 57 held in' the groove 58, by means of thescrews Projecting 'from' the sleeve at one side thereof is a lug 60, upon which is clampedv by'means of screw 61,tlie rear!` `\var'dly`'etending arm 62 of the indicator 62. rl`he indicator is provided with a downwardly extending stem 64, the lower end of whichy engages a member 65, secured upon the' outer end of the lever 33, by means of a bolt 66, as shown in Figures l and Vl. Se

cured upon the lower end of thefsleeve cator maybe of any preferred type, butd preferably comprises a graduated dial with.

a pointer actuated by a spring, controlled by the stein 64, which when moved inwardly will cause the pointer to indicate the diiference between the desired and actual distance between the sides of the adj aceut splines or j projections.

In, the operation ofthe machine, bearing in mind that the indicator hand normally lies at a point to the left of the zero mark upon the dial, when the lever 33 lightly contacts with the stem 64, and assuming that the adjustable screw 41 has been set in the proper position, the reamer is applied in posit-ion to be supported by the pins 14 and 17, and is then turned by hand counter clockwise to the position shown in Figure Vl, until the upper edge of the spline 16 comes in contact with the linger 46. Upon further turning of the reamer the outer end of the lever 33 will be raised', at which time the pointer will `begin to move to the right and if it reaches the Zero point on the dial at the same time that the upper end of the splinel comes in contact with the end of the pin 41 the operator will know that the splines are spaced apart the correct dis-- tance but if when the pointer moves to the Zero position and the lower spline 16l has not yet come in contact with the pin 41 he will know that the distance between the splines is too great, while on the other hand if the lower spline 16 comes in contact with the end of the pin 41 before the pointer reaches the zero position. it will indicate that the distance between the splines is not great enough. The extent of the increase or decrease of the distance between the splines above or below the proper amount will be indicated by the4 number of graduations' upon the dial between the indicator hand and the Zero point, in one lcase at' the time when the spline 161 comes in contact with .the screw 41 before the spline 16 comes in contact with the linger 46, in the other case lll".

liu

will show a plus reading. The indicator shown in the present instance is one which is provided with a rotating dial so that when the pointer is in the position it normally assumes the dial may be rot-ated to the right or lett to shift the zero point the desired amount. y

While I have illustrated and described one embodiment ofmyiinvention it will be obvious to those skilled in the art that other embodiments and modifications thereof may be constructed without departing from the spirit of the invention and l wish therefore not to be limit/ed or restricted to the pre*- cise embodiment shown except in so far as the same is limited by the appended claims.
